将展平的存储过程值映射到导航属性

Question

这是我的存储过程，它返回一种 Customer_GetCustomers_Result：

SELECT c.*, a.City AS AddressCity, a.State AS AddressState
FROM Customer c
LEFT OUTER JOIN Address a ON c.AddressId = a.Id

当使用 AutoMapper 从 Customer_GetCustomers_Result 映射到 Model.Customer (POCO) 时，我希望 AddressCity 和 AddressState 映射到 Customer.Address.City 和 Customer.Address.State。

我认为使用这个命名约定我不必在我的 AutoMapper 配置中添加任何特殊的东西，除了：

CreateMap<Customer_GetCustomers_Result, Model.Customer>();

我愿意做任何事情来从我的存储过程中获取要映射的导航属性。有什么想法吗？

你可以使用AfterMap:

Mapper.CreateMap<Customer_GetCustomers_Result, Model.Customer>()
    .AfterMap((s,t) => 
    {
        t.Address = new Address { 
                                    City = s.AddressCity, 
                                    State = s.AddressState
                                };
    });

或者甚至定义第二个映射...

Mapper.CreateMap<Customer_GetCustomers_Result, Address>()
    .ForMember(t => t.City, m => m.MapFrom(s => s.AdressCity))
    .ForMember(t => t.State, m => m.MapFrom(s => s.AdressState))

然后……

Mapper.CreateMap<Customer_GetCustomers_Result, Model.Customer>()
    .AfterMap((s,t) => 
    {
        t.Address = Mapper.Map<Address>(s);
    });
